IMPROVEMENT IN LUBRIGATING- JOURNALS.

The Schedule referred `to in these Letters Patent and making part of the sam.

TJ all u-hom it may concern Be it known that I, CHARLES BEAN, of' Providence, in the county of Providence and State oflthode Island, have invented a new and useful Improvement in LubricatingJoui-nals; and I do herebydeclare that-the following is a full, clear, and exact description. thereof, which will enable others skilled in the art to make and use the same, reference being had to .the accompanying drawing forming part of this specification,

This invention relates to a new a-nd useful improvement in the method of oiling or lubricating the journals of revolving shaft-ing and journals generally, and consists in conveying oilito th'e journal from au open drip-pan beneath the journal through a tube, by means of capillary attraction, so arranged as to filter the gudgeon or drip oil fromlall impurities, and deliver it to the bearing, as will be hereinafter more fully dcscribed. 4

The accompanying drawing represents a -vertical section of a shaft-hanger, showing the boxes and the shaft, and also the drip-pan, in red color, with my iu` bricat-ing device attached thereto.

Similar letters of reference Iindicate corresponding parts.

A is the lubricating tufbe, which may hc of any con venent size and of any shape, as round, dat., or oval.

It is bent so as to .enter the drip-pan beneath the hanger, .and curve upward around the outside of the box, and enter the cap'of the box, as seen in'the drawing.

B represents a piece of candlelwicking, or other porous or fibrous material, which is drawn'througb the tube, with its lower` 'c nd immersed in the oil, which is placed in the drip-pam and with its upper end resting on the journal or co tained in the aperture in the cap, so that the oil or llubricating material may be conveyed directly to the journal.

To accomplish this it may not perhaps be necessary for the end of the capillary to bein actual contactv with the journal, but if:A in contact the oivlwould be more rapidly' discharged, as something of a vacuum would be created by the revolving journal, which would induce a more ije discharge of the oil.

Over the lower end of the tube, and inclosing the lower end of the wick or capillary B, is a' bag, C, of some fibrous or porous material, for straining the oil before it is taken upto the journal.

. As the pan is placed so as to catch any drip from the journal, the quantity carried up may be-more than spiiicient to properly lubricate the journal, but no waste can occur `therefrom, while t-he dust, which might settle in the pan, can do no injury, the oil being strained clean before entering'the tube.

The impure or gudgeon oil falling from the bearing when overcharged, enters vthe drip-pau and is again deliveredto the jourualin as pure a state as when iirst applied. By this constant ow ofoilthrough the journal, it is kept cleanaud free from dust and yrit, all of which accumulates in the reservoir, from whic it should be from'timeto time removed.

I do not broadly claim lubricating a journal by means of capillary attraction, as I am aware that it has been done before, but I am not aware that a capillary inolosed in a tube has taken pure oil from a drip-pan, carried and delivedcd it to the journahas labove described, before my present invention.l

-Having thus described my invention,

WhatI claim as new, and desire to secure "by-Letters Iatent, is-

The journal lubricator herein described, consisting of the bent'tube A, containing the capillary. B, and provided with strainer C, arranged as described, for

conveying the oil from the drip-pan, and deliering it, freed from all impurities, to the bearings,substantially as set forth,

' CHARLES BEAN.
